<abstract xmlns="http://www.w3.org/1999/xhtml"><p> Objective: The aim of our study was to determine the relation of particular genetic variants in selected genes (GSTM1, GSTT1 null genotypes; rs1695 GSTP1; rs10735781 EVI5) to the risk of multiple sclerosis (MS) development and find out the possible association with disease disability progression rate. Material and methods: Our study included 202 MS patients and 174 healthy control volunteers. MS patients were divided according to disability progression rate to three groups - slowly progressing, mid-rate progressing and rapidly progressing. All DNA samples were isolated from venous blood. Genotyping was performed by PCR-RFLP and multiplex PCR. Results: Our analysis showed that GSTT1 null genotype (OR 0.56; 95%CI 0.33 -0.95; p=0.04) and GSTM1, GSTT1 double null genotype (OR 0.32; 95%CI 0.14 - 0.74; p=0.006) are potentially protective in relation to MS. We observed similar result in GSTT1 null genotype in association with mid-rate progression (OR 0.48; 95%CI 0.24 - 0.97; p=0.05). Frequency of GSTM1 and GSTT1 double null genotype is significantly lower in subgroup of MS patients with progression rate defined as slow (OR 0.22; 95%CI 0.05 - 0.98; p=0.05) and middle (OR 0.33; 95%CI 0.11 - 0.99; p=0.045). We did not show any significant association of genetic changes rs1695 in GSTP1 and rs10735781 in EVI5 with MS or rate of disease progression. Conclusions: Genetic basis of multiple sclerosis is still not fully elucidated. Further research may clarify our results and confirm the value of studied factors for clinical practice.</p></abstract>
